Atos reduced engine power

Greetings. The symptoms you describe indeed point towards a potential throttle body issue. The 'reduced engine power' and the illuminated 'check engine light' are common indicators. The throttle valve, responsible for regulating air intake, can cause such problems when malfunctioning. It is as if the engine is trying to breathe through a constricted airway. Have you observed any response delay from the accelerator pedal? Knowing this would help to narrow down the possibilities.

Thanks for the quick reply. Yes, there is a definite response delay when I press the accelerator. It's not immediate like it used to be. Does this confirm the throttle valve issue?

Yes, the presence of a response delay reinforces the likelihood of a defective throttle valve or associated components. The delay, coupled with the reduced power and warning light, suggests the car might be entering a 'limp mode' to prevent further damage. Given the car's mileage (57870 km), wear and tear could certainly be a factor. It would be prudent to take it to a qualified workshop for a thorough diagnosis and repair. Continuing to drive with this issue could potentially exacerbate the problem. Based on the probable cause you cited, the repair cost will be around 265€.

Understood. Thanks for confirming my suspicions and providing the cost estimate. I appreciate the detailed explanation. I'll get it to a workshop ASAP. It turns out, the accelerator pedal module was indeed defective, and after replacement, everything is working as it should again.
